FEED-WATER PU RIFIER.

SPECIFICATION forming part of Letters Patent No. 583,786, dated June 1, 1897.

Application filed October 29,1896. Serial No. 610,431. (No model.) Patented in Denmark July 24, 1893, No. 361, and in England March 26, 1895, No. 14,314, and May 8,1896,N0. 9,844.

To all whom it may concern:

Be it known that I, JULIUS BRUUN, machinist, of Raadmandsgade 24, Copenhagen, in the Kingdom of Denmark, have invented certain new and useful Improvements in or Relating to Feed-Water Purifiers, (for which I have obtained Letters Patent in Denmark, No. 361, dated July 24, 1893, and in Great Britain, No. 14,314, dated March 26, 1895, and No. 9,844,

dated May 8, 1896,) of which the following is a specification.

This apparatus has for its object to remove automatically from feed-water for steam-boilers such matters as may produce sediment or incrustation, toprevent said matters entering the boilers, and to admit only pure water. The apparatus is applicable where crude or natural water is used for feeding. The purifying process consists in adding a suitable chemical solution or reagent for any special kind of water, and in cases where the reagent is apt to cause a sediment if not stirred upfor instance, by lime-milk, &c.-- the arrangement is somewhat different from 2 5 the arrangement in cases where the reagent remains in a state of perfect and constant solution.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar characters of reference denote corresponding parts in all the views.

Figure 1 is a sectional view of the apparatus on the line 1 1 of Fig. 2. Fig. 2 is a sectional view on the line 2 2 of Figs. 1 and 3.

is a plan View of the apparatus for use in connection with a reagent inperfect and constant solution. Fig. 4 is an end elevation of the apparatus for use in connection with a reagent not in perfect and constant solution and requiring agitation, and Fig. 5 is a longitudinal section of the form of the invention shown in Fig. 4.

Referring to Figs. 1, 2, and 3, the apparatus consists of a container A for the reagent. This container has a foot-valve D at its base, which discharges into a balanced oscillating receiver B, consisting of two chambers b b and revoluble about its pivots S5, which are mounted in a suitable frame T, situated in Fig. 3'

the upper part of a filtering-tank E or otherwise conveniently located. 7

The natural water to be treated is led direct through an inlet-pipe H into one of the chambers, say I), of the balanced oscillating receiver B, and when this chamber is filled the center of gravity is moved and the receiver oscillates in such manner as to pour out its contents into the tank E below, bringing the other chamber 6 below the orifice of the pipe H. A lever C is pivoted at c to the receiver B, and this lever C is in turn pivoted to the lever O, to which the stem or spindle a of the valve D is attached by a nut S.- By these means the valve D is operated at each oscillation of the receiver B. The lifting motion of the valve D is variable by means of the nut S on its spindle a. Owing to the oscillating movement of the receiver B through these said adjustable connections 0 O and spindle a,the container foot-valve D is opened and closed, and thereby any predetermined quantity of the reagent is allowed to fiow through the pipe dand discharge into one of the chambers, say 6, of the oscillating receiver B.

The movement of the receiver B is ,r *ulated by suitably-disposed stops, 9,10% t, by which the discharge and quantit of re- I agent necessary to separate the stony ingredients from predetermined volumes of the So Water under treatment is determined.

That side of the receiver B which is filled with water through the inlet-pipe H descends and the container-valve D opens simultaneously, admitting the reagent solution at each operation, whereby a fixed quantity of natural water is automatically mixed with a certain quantity of reagent each time the receiver oscillates and pours the mixture out into the lower tank E. In this tank the sep- 0 aration of the stony or deleterious matter takes place. These are precipitated to the bottom while the pure water ascends through a superposed filterK, which may consist of wood flock, hay, mats, or the like, (placed on 5 a suitable frame 70, as shown,) which will permit the water to pass on freely, but arrest the passage of any small light particles of reagent or matter which may be suspended in the water. After having passed through this filter the water is purified and may then be led through a delivery-pipe e to the feedwater vessel or directly to the suction-pipe of the feed-pu mp.

hen the reagent is, for instance, limemilk or any other mixture which is apt to cause a sediment and does not remain in a perfect and constant solution, the container is made in form of a cylindrical vessel or drum A, as shown in Figs. 4 and 5. The drum A is arranged in such a manner that it may oscillate on trunnions w as, supported in hearings on a suitable frame. The tank A is, by means of a rod Y, connected with the oscillating receiver B in such a manner that whenever the receiver B oscillates the tank A will also make a corresponding movement to and fro around the trunnions a; 0:.

As in the first-mentioned arrangement, the tank A is provided with a foot-valve D, attached to a spindle a, which foot-valve may be operated by means of a system of levers G, G, and C, as in the first-mentioned arrangem ent. The inside of the oscillating tank is also provided with projecting ribs or wings Z Z for the purpose of constantly stirring up and agitating the sediment of lime or other sediment that may sink to the bottom thus keeping the mixture in a state of perfect and constant solution.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, of a container having an outlet, a valve controlling the outlet, an oscillating receiver adapted to contain the substance discharged from the container, a feed-pipe independent of the container and arranged in operative relation to the receiver, so that different substances maybe discharged into the receiver from the feed-pipe and from the container respectively, and a connection between the receiver and valve, whereby the valve is operated, substantially as described.

2. The combination, of a container having an outlet, a valve controlling the outlet, a movable receiver adapted to contain the substance discharged from the container, a feedpipe independent of the container and arranged in operative relation to the receiver, so that different substances may be discharged into the receiver from the feed-pipe and from the container respectively, a connection between the valve and receiver, and a tank adjacent to the receiver, substantially as described.

3. The combination of a container having an outlet, a valve controlling the outlet, a feed apparatus, a feed-pipe independent of said container and leading to the feed apparatus so that different substances may be discharged from the container and from said feed-pipe, respectively, and a connection between the feed apparatus and the valve whereby the valve is operated by the feed apparatus and in unison therewith, substantially as described.

4. The combination of a container having an outlet, a valve controlling the outlet, a movable feed apparatus in connection with the valve and actuating the same in unison with the movements of the feed apparatus, and a feed-pipe independent of said container and leading to the feed apparatus so that different substances may be discharged from the container and from the said feed-pipe respectively, substantially as described.

5. The combination of a container with an opening, a valve controlling the opening, an oscillating feed apparatus, a connection between the feed apparatus and the valve by which the valve is operated in unison with the feed apparatus, a feed-pipe independent of said container and leading to the feed apparatus so that difierent substances may be discharged from the container and from said feed-pipe respectively, and a tank located beneath the feed apparatus and receiving the water from the feed apparatus, substantially as described.

6. The combination of a container with an outlet-orifice, a valve controlling the outletorifice, a movable feed apparatus, a connection between the feed apparatus and the valve, whereby the valve is operated in unison with the movement of the feed apparatus, a tank located beneath the feed apparatus, and a frame held within the tank and immediately below the feed apparatus, the frame serving to limit the movement of the feed apparatus, substantially as described.

7. The combination, of a container having an outlet, a valve controlling the outlet, a tank adapted to receive water and the purifying substance from the container, a connection from the container to said tank, a feed apparatus for delivering water to said tank, and a connection between the container-valve and the feed apparatus in such a manner as to automatically bring a predetermined amount of purifying material together with a certain amount of water in the purifying-tank, substantially as described.

8. The combination of a movable container, a movable feed apparatus, adapted to discharge water into a tank or the like, a connection between said container and feed apparatus to cause them to move in unison,and means for discharging a predetermined portion of the contents of the container at each movement of the feed apparatus, substantially as described.

9. The combination of a movable container, a movable feed apparatus, adapted to discharge water into a tank or the like, a connection between said container and feed apparatus to cause them to move in unison and a valve located upon the container and operated by each movement of the feed apparatus to discharge a predetermined portion of the contents of the container, substantially as described.

10. A container having an outlet, a valve controlling said outlet, a valve-opening mechanism having an adjustable connection With the Valve-stem to regulate the throw of the valve and the amount discharged at each operation thereof, a movable feed apparatus adapted to discharge Water into a tank or the like, and an operative connection controlled by the movement of said feed apparatus, for

causing the valve to be opened at each move- IO ment thereof, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.
